QBasic (Microsoft Quick Beginners All purpose Symbolic Instruction Code) is an IDE and interpreter for a variant of the BASIC programming language which is based on QuickBASIC. Code entered into the IDE is compiled to an intermediate form, and this intermediate form is immediately interpreted on demand within the IDE. It can run under nearly all versions of DOS and Windows, or through DOSBox/DOSEMU, on Linux and FreeBSD. For its time, QBasic provided a state-of-the-art IDE, including a debugger with features such as on-the-fly expression evaluation and code modification.
Like QuickBASIC, but unlike earlier versions of Microsoft BASIC, QBasic is a structured programming language, supporting constructs such as subroutines and while loops. Line numbers, a concept often associated with BASIC, are supported for compatibility, but are not considered good form, having been replaced by descriptive line labels. QBasic has limited support for user-defined data types (structures), and several primitive types used to contain strings of text or numeric data.
QBasic was intended as a replacement for GW-BASIC. It was based on the earlier QuickBASIC 4.5 compiler but without QuickBASIC's compiler and linker elements. Version 1.0 was shipped together with MS-DOS 5.0 and higher, as well as Windows 95, Windows NT 3.x, and Windows NT 4.0. IBM recompiled QBasic and included it in PC DOS 5.x, as well as OS/2 2.0 onwards. eComStation, descended from OS/2 code, includes QBasic 1.0. QBasic 1.1 is included with MS-DOS 6.x, and, without EDIT, in Windows 95, Windows 98 and Windows Me. Starting with Windows 2000, Microsoft no longer includes QBasic with their operating systems. However, some localized versions of Windows 2000 and Windows XP still have it, and it can be given out as freeware.

Game NOT Working (Part II)
Now, THIS game won't work online, either! Got the same error message: "Failed to download game data!" Is this problem widespread throughout the WHOLE site? I DEMAND that an investigation be opened, because there are lots of people out there, like me, who rely on this site to stream and play older games online, and those same people are soon bound to start COMPLAINING as soon as this problem is discovered by more and more people! So PLEASE...FIX THIS PROBLEM NOW!!! :-(
